Construction and characterisation of the DarkSide-20k veto silicon photo-multiplier tiles

Fabio Acerbi, Pushparaj Adhikari, P. Agnes, Iftikhar Ahmad et autres

Abstract Silicon photo-multipliers (SiPMs) are state-of-the-art sensors capable of detecting a single photoelectron under cryogenic conditions, with potentially lower radioactivity than widely used photomultiplier tubes. The DarkSide-20k experiment, designed to perform direct dark matter searches using liquid argon as the target material, …

Sensitivity to low-mass WIMPs with an improved liquid argon ionization response model within the DarkSide program

Fabio Acerbi, P. Adhikari, P. Agnes, Irshad Ahmad et autres

Dark matter detection experiments using liquid argon rely on a precise characterization of the ionization response to nuclear recoils, especially in the keV energy range relevant for light dark matter interactions. In this work, we present a comprehensive analysis that combines new …

Demonstration of the light collection stability of a PEN-based wavelength shifting reflector in a tonne scale liquid argon detector

Vipin Prakash Gupta, G. R. Araujo, M. Babicz, L. Baudis et autres

Abstract Liquid argon detectors rely on wavelength shifters for efficient detection of scintillation light. The current standard is tetraphenyl butadiene (TPB), but it is challenging to instrument on a large scale. Poly(ethylene 2,6-naphthalate) (PEN), a polyester easily manufactured as thin sheets, could …

DarkSide-20k sensitivity to light dark matter particles

Fabio Acerbi, P. Adhikari, P. Agnes, I. Ahmad et autres

The dual-phase liquid argon time projection chamber is presently one of the leading technologies to search for dark matter particles with masses below 10 GeV c−2. This was demonstrated by the DarkSide-50 experiment with approximately 50 kg of low-radioactivity liquid argon as …
